This subheading captures a range of birds including spent hens, roasters, and specialty breeds sold through live poultry markets, as well as birds transferred across the US-Canada border for further grow-out or processing. Day-old and very young chicks are excluded and classified under the 185-gram-or-less subheadings.

The core permit and health certificate requirements are the same regardless of weight, but heavier birds may require more detailed physical inspection and are subject to the same quarantine authority if disease concerns arise. Importers should ensure transport conditions meet APHIS animal welfare standards, which become more operationally complex for larger, older birds than for day-old chicks.
